last Monday i took my car out to the race track for practice, i drive a HPI Sprint, after i got done racing, i came home charged the battery and ran the car again, when i hit the throttle, the car started shaking badly, i came back inside and took the body and wheels off and ran the car and it still shook, so i know its not the tires being to worn on one side. The rear of the car shakes really bad when i run it as if something was very loose, but i checked all my screws, connections and belts but nothing seemed out of place. All i can think of is that my chassis is bent somewhere, but my level ruler deosn't show any imbalance. I just can't find what causing it to shake like so.

If you push the chassis by hand does it still wobble? mabey you bent a stub axel or a cvd. when you were at the races did you hit any thing?

no when i push the chassis is does not wobble, but when i run it the rear seems to shake and theres a knocking noise comeing from the rear.

have you checked the motor? maybe something came loose inside. i once had a wire come loose on a 9 turn motor. try taking the motor out and running it by itself to see. just a thought

i ddi that but it doesnt shake, BUT i have foudn whatys is causing it to shake, the front belt, theres this little wheel, i dunno what its called, but i call it a pinion wheel, that sits on the front belt to keep it runing strait cause its so long, well i re-adjusted the wheel and put more pressure on the front belt and sure enough the car stopped shakeing.
